DYEING APPARATUS AND THE LIKE.

Application filed April 7, 1917.

To all whom it'mag concern:

Be 1t known that I .Lno G. GRABE a citizen of the United States Of',A.IH6I1Ct1,l' 1

siding at St. George, Richmondfcounty, State of New York, have invented certain new and useful Improvements in Dyeing Apparatus and'the like, ofwhich the following is a full, clear, and exact description.

This invention relates to improvements in apparatus for dyeing fabrics or other similar goods, the object. of my invention being to provide an inexpensive but eflicient device which can be used for household purposes or by those not skilled in the art of dyeing. My improved dyeing apparatus, briefly stated, comprises a suitable vessel within which is placed a circulating device designed to cause the circulation cfthe dyeing liquid within the vessel by the aid of steam pressure, the steam being generated by the heatingof the liquid over a flame, or by injecting live steam into the vessel. The action of the device toeffectively perform the dyeing'operation depends upon the action of the boiling liquid." The circulating device which I employ consists of a hollow conoidal vessel. having a perforated wall through which the boiling liquid, mixed with air, will pass into the vessel. The liquid within the vessel will rise to the top thereof and be discharged into a mixing chamber, from whence it will pass into the vessel containing the articles to be dyed. The circulating device, as well as the articles to be dyed, will be submerged in the dyeing liquid.

I will now proceed to describe my inven tion in detail, the novel features of which I will point out in the appended claims, reference being had to the accompanying drawings, forming part hereof, wherein Figure 1 is'a vertical sectional view of my improved apparatus, the circulating device being illustrated partly in elevation;

Fig. 2 is an enlarged sectional plan view, the section being taken on' a line 2-2' in Fig. 1';

view, the section being taken on a line 6-6 in Fig. 1.

As herein embodied, my improved apparatus consists of a vessel 7 to contain a liquid and the articles to be dyed. Within the vessel 7, Iplace a conoidal hollow circulating device 8, the function of which is to cause the liquid to circulate. To aid in the circulation' of the liquid, I preferably employ a helically disposed-vane 9 which is fastened to the inner surface of the wall of the vessel as shown.

in the upper end of the vessel 7, I place a mixing-chamber 10 having an open bottom covered by a screen 11. Adjacent the mixingchamber 10, 1 locate a condensing chamber 12 having inlet passages 13 and 1%, which admit vapor to the interior 15 of the chain ber 1-2. To permit the condensed vapors to fall back into the vessel '7, I provide the bot tom 16 of the condensing chamber 12 with openings 17.

Intermediate the top and bottom of the vessel 7, I place a screen 18, which acts to prevent the articles immersed in the liquid in the lower part of the vessel from being forced out of the said liquid, but not to prevent the return of the liquid during the action of the circulation thereof.

As can be seen, the upper end 19 of the circulating deviceprojects'through the screen. 18 and into a duct 20, the said duct being in communication with the mixing-chamber 10. As has already been stated, the circulating device 8 is hollow, and is made with a corrugated wall, the space between the corrugations being perforated as at 21. The corrugations 2'2- prevent the article being dyed from closing the openings, and hence unobstructed circulation is at all times provided for- During the dyeing operation, the boiling water, mixed with air, will be forced into the interior of the circulating device through the openin s 21. As the. circulating device is virtually a chamber, the hot liquid within the same will rise to the top (being greatly assisted by the pressure of the vapor), and passthrougb the duct 20 into the mixingchamber 10, from which it will escape through the screen 11 intothe body of the vessel 7. The circulation of the liquid will.

be a continuous stream in the path just described. Should the dyeing element and water tend to separate, they will. be thoroughly mixed as they pass through the screen 11. The chamber 10 collects the liq- The vapors that r be a duct having a as can scan. [r hamber 10, duct 20 and circulating ice or chamber 8, and termina tes adj a cc 7. The duct 11 connects the lower poi: t the upper portio 3 thereof. lVhile in operation, the vessel will he closed at the t p thereof by a cover 25.

The above mentioned combination of elements tends to thoroughly' impregnate the articles to be dyed with the dyeing element, especiallv the said element violently agitated and forced against and through the said artic as by the action the irculatins: devic it will, of course, he understood that in hot steam into the vecunion 26 which of the duct improved apparatus can also be utilized for disinfection, washing or other purposes,

wherever thorough p netration into fabrics of steam or boiling fluid needed, and wherever in the foregoing specification and claims speak of dyeing apparatus, there is no intention to limit the use of the device to any particular pur ose.

ll hat l claim as 'nv i vention is:
